Senior frontend engineer building scalable React web & mobile apps.
What I'm looking for
I’m a Senior Frontend Engineer with 4 years of experience building scalable, high-performance web and mobile applications. I enjoy leading frontend architecture decisions, large-scale migrations, and shipping production-grade experiences at scale with a strong focus on performance, accessibility (a11y), and quality.
At DealShare, I optimized cart and payment flows through code splitting and bundle optimization, reducing load time by 34%. I also migrated 5+ legacy Angular dashboards to React, drove a scalable design system and component library that reduced bundle size by 90%, and established a testing strategy with Jest, Playwright, and Cypress to significantly reduce regressions.
I’ve also delivered end-to-end impact through secure feature development and measurable platform improvements—like deep-linking that reduced onboarding provisioning time by 90%, a Webpack to Rspack migration that cut build time by 93.99%, and payment reliability work (including a circuit breaker) that lifted payment success conversion by 18%. Whether it’s instrumentation via Google Tag Manager/Google Ads, CI/CD-minded engineering practices, or mentoring junior engineers, I’m at my best when I can connect architecture, implementation, and outcomes.
